Job #1 would be to check that the speaker cable isn't/wasn't shorted. Sometimes they can short out if bent a particular way.

When you say "blew," what does that mean? Won't power up? Powers up but no sound? If it powers up but there's no sound, is there anything coming from the preamp output (or effects out)?

Was there a smell or a noise before it happened?

Is the fan (if there is one) working?
